Reset Byte Each running time meter is assigned a bit in the reset byte. Using the
reset byte, the controller can reset the running time meters in the oper-
ating device.
If bit X is set in the reset byte when polling is carried out, the running
time meter X is reset to 0.
Polling Time You use the polling time to specify the time intervals at which the oper-
ating device reads from the controller the variables for the control byte
and the reset byte.
The running time meters are activated in the operating device as soon
as you have entered a variable name for the control byte and specified
a value for the polling time. If the polling time is 0 or if there is no
address for the control byte, the Running Time Meter function in the
operating device is off.
Transferring counter value For each running time meter, you can enter a variable name in the con-
troller. The operating device stores the value of the corresponding run-
ning time meter if the controller requests that the operating device to do
so.
For this purpose, the controller writes the hexadecimal code 7FCF into
the serial message channel of the polling area.
For each variable, a 32-bit memory area must be available in the con-
troller!
